A qualitative risk assessment of Crimean-Congo haemorrhagic fever in Nigeria: implications for One Health response.
Article in International health, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 papers, 1 of them a synthesis that pooled it.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundCrimean-Congo Haemorrhagic Fever (CCHF) is a severe tick-borne viral disease. Increasing cases in West Africa suggest potential undetected circulation in Nigeria.
methodsA One Health Joint Risk Assessment was conducted to identify transmission pathways and assess the likelihood and impact of human CCHF infections at the human-animal-environment interface in Nigeria. Risk framing involved developing structured questions for potential Crimean-Congo Haemorrhagic Fever virus (CCHFV) transmission scenarios. A scoping review was conducted and median seroprevalence values were reported. The likelihood, impact and data uncertainty for human infection scenarios were used for a qualitative estimation of risk.
resultsHuman contact with infected livestock during farming, veterinary practices and exposure to ticks was identified as a key infection route. Most cases in Nigeria (66.7%) were identified via serology, with a median human seroprevalence of 6.1% and cattle seroprevalence of 30.2%. CCHFV has been isolated from Rhipicephalus ticks. Four risk assessment questions were defined and focused on veterinarians, abattoir workers, herders, wildlife rangers and healthcare workers. Animal-related professions had a moderate likelihood of infection.
conclusionStrengthening One Health surveillance, vector control and multisector infection prevention is crucial to reducing the risk of CCHF and averting future outbreaks.
